PHYS SEMINAR:Exploring Galaxy Cluster Evolution at Subparsec...
Galaxy clusters are the largest (Mpc) and the most massive (1014 1015 Msolar) virialized objects in the universe embedded in the deep potential well of dark matter (DM) halos. Galaxy clusters host hundreds of galaxies surrounded in an extremely hot (107 108 K) and tenuous (10-5 10-1 cm-3) plasma, i.e., the intracluster medium (ICM). The giga-years-long evolution of these structures are intimately linked to the dynamics of their constituents (supermassive black hole activity, stellar feedback, galaxy evolution) as well as the dynamics arising from the mergers of galaxy clusters themselves (shocks, turbulence, non-thermal processes).Yet, how these mechanisms shape galaxy clusters is not well understood. The ICM, which primarily shines in the X-ray regime, is the reservoir that keeps a record of the past dynamical activity due to the DM potential. Therefore, X-ray studies of galaxy clusters hold immense potential to unravel the choreography of physics acting at a millionfold different physical scales. In this talk, I will present my research on probing galaxy clusters from the central active galactic nuclei (parsec) to the intercluster filaments (megaparsec) using X-ray data and I will share my academic journey leading up to my involvements in the state-of-the-art X-ray elescope mission XRISM and what the future holds for X-ray Astronomy.
